(EWSI) (then known as Atlantic Orient Corporation or AOC) developed an advanced 50 kW wind turbine which produces energy at competitive rates for distributed generation, village electrification, diesel-based utilities and purchased power displacement for agriculture, industry and municipalities. AOC based its design on the Enertech E44 series wind turbines, of which approximately 750 were built between 1982 and 1986. They were installed in wind power stations throughout the United States, as well as in several other countries. Most are still in operation today. AOC evaluated the historic performance of a significant number of E44 series wind turbines, identifying problem areas and ranking them according to their impact on turbine downtime. Specific downtime related issues were then targeted and solutions proposed. The impact of the various solutions was then evaluated on an economic and risk basis to further define the benefits of each improvement. Resulting from this analysis, AOC developed a preliminary design for a 50 kW wind turbine: the AOC 15/50. The results obtained were so encouraging that the final design and prototyping of the AOC 15/50 were initiated under separate NREL contracts. The Dutch National Laboratory for Renewable Energy (ECN) performed an independent reliability analysis concluding that the AOC 15/50’s design was sound. After an extensive review and analysis of the operating histories of existing wind turbines, AOC's design team incorporated many design features in the AOC 15/50 to enhance its energy production. These features included: Ž Advanced modified NREL thick airfoils Ž Electromagnet controlled tip brakes Ž Single piece hub casting Ž Innovative slip ring to transfer power to the tip brakes Ž Integrated gearbox with improved internal components Ž Totally-enclosed generator Ž Single piece cast tower top with larger yaw bearings Ž Uniformly tapered galvanized lattice tower Ž Advanced controls based upon a microprocessor controller Ž Ethernet communication module for remote monitoring In September 2004, Entegrity Wind Systems Inc. (EWSI) assumed the assets of Atlantic Orient Corporation and officially changed the machine name to the EW15 from the AOC 15/50. The remainder of this information package will refer to the company as EWSI and will be updated soon to reflect the change of name of the machine in the foundation and tower load drawings. All information on the wind turbine is current. NOTICE: All content subject to notes and disclaimers specified on page 1 of this manual. © 2006 Entegrity Wind Systems Inc. 3 Figure 1-1 illustrates a typical EW15 Wind Turbine Generator (WTG). The designation 15 refers to the turbine’s 15 m diameter rotor and its rated output of 50 kW. The rated output is reached at wind speeds of 12 m/s (26.8 mph) for the 50 Hz WTG and 11.3 m/s (25.3 mph) for 60 Hz WTG. As shown in the power curve in Figure 1-2, the wind turbine is designed to cut in at 4.6 m/s (10.2 mph). The turbine is stall regulated and at about 15 m/s reaches its peak output of 55 kW for the 50 Hz WTG and 66 kW for the 60 Hz WTG. Assuming 100% availability and average wind speed of 6.7 m/s (15mph), it is calculated to produce 145,000 kWh/year for the 50 Hz WTG and 153,000 kWh/year for the 60 Hz WTG. Figure 1-3 illustrates the projected net annual energy production as a function of average annual wind speed. Full specification for both the 50 Hz and 60 Hz configurations are given in the appendix. Figure 1-1 EW15 WTG NOTICE: All content subject to notes and disclaimers specified on page 1 of this manual. © 2006 Entegrity Wind Systems Inc. 4 NOTE: The power curves show the typical power available at the controller based on a combination of measured and calculated data. Annual energy is calculated using power curves and a Rayleigh wind speed distribution. Energy production may be greater or less depending on the actual wind resources and site conditions and will vary with wind turbine maintenance, altitude, temperature, topography and the proximity to other structures including other wind turbines. Figure 1-2 EW15 Power Curve Figure 1-3 EW15 Projected Net Annual Energy Production NOTICE: All content subject to notes and disclaimers specified on page 1 of this manual. © 2006 Entegrity Wind Systems Inc. 5 The EW15 has been designed as a robust, economical, low-maintenance wind turbine to be utilized in extreme environments. The tower top casting provides a rigid, low cost interface between the gearbox and the tower. The low speed shaft has a sufficiently large diameter and the necessary material strength to accommodate the structural and fatigue loads encountered during operation. The hub consists of a single piece casting for design simplicity. See Figure 1-4 A more detailed view of the turbine assembly is provided in Figure 1-5. The design team aimed for design simplicity. The heart of the design is the integrated gearbox consisting of a single piece, cast housing. The generator is flange-mounted to the planetary gearbox with the enclosed parking brake directly coupled to the totally enclosed generator. There is no nacelle. Figure 1-5 EW15 Drive Train Assembly Figure 1-4 EW15 Drive Train Assembly NOTICE: All content subject to notes and disclaimers specified on page 1 of this manual. © 2006 Entegrity Wind Systems Inc. 6 The EW15 aerodynamic tip brakes are latched or released by electromagnet when triggered by the control system. A spring return device assembly is incorporated to return the tip brake to closed position. All components are designed for fail-safe operation. See Figure 1-6 below. The EW15 uses an induction generator and can be easily interconnected to an electric utility network (3 Phase, 400 to 600 VAC) or a diesel grid. The details of your installation will be based on the requirements of the interfacing network and/or the local utility. A Single Phase turbine is in development and expected to be field ready in 2007-2008 2.0 Research, Development & Field Testing The EW15 represents the latest technology in highly reliable, affordable turbines. Our design effort is fully supported by design tools, which include FLAP, PROP, YAWDYN, ADAMS and Algor for finite element analysis. EWSI maintains a test facility for continuous testing of key system components. Drive train components, generators, control systems and braking systems have been thoroughly evaluated under a range of loading conditions. Furthermore, long term testing and research continues to provide EWSI with data to refine modeling and analysis techniques, as well as to verify the performance and reliability of its products. Over the past twelve years, EWSI has been involved with a series of test wind turbines in various climates. Some of these wind turbines have been instrument-equipped for structural load evaluation. Locations of these turbines included Palm Springs CA, Rocky Flats CO, Bozeman MT, Bushland TX, South Burlington VT, Scotland, and the Atlantic Wind Test Site Figure 1-6 EW15 Wind Turbine with Tip Brakes Deployed NOTICE: All content subject to notes and disclaimers specified on page 1 of this manual. © 2006 Entegrity Wind Systems Inc. 7 on Prince Edward Island, Canada. EWSI, in cooperation with the United States Department of Energy and Kotzebue Electric Association Alaska, has developed a small wind farm during the past six years with twelve EW15s. See Figure 2-1. The project is located in Kotzebue, north of the Arctic Circle, and was monitored and evaluated for performance by the DOE and EPRI Wind Turbine Verification Program.1 To date, commercial wind turbines have been located in Canada's Northwest Territory, Northern and Southern Ontario, Saskatchewan, Prince Edward Island, Alaska, Central Russian Siberia, Argentina, Maine, New Hampshire, Texas, North Dakota, Vermont, New York, United Kingdom and Morocco.

Site Factors Site selection may have a significant effect on annual energy production. It is worth the additional time and effort to locate the proper site to maximize energy production. The following site factors should be considered: Ž Wind resource characteristics Ž Average wind speed Ž Frequency and duration of power producing winds Ž Prevailing wind direction Ž Turbulence Ž Peak wind speed Ž Height and location of obstructions Ž Distance from utility service Ž Local height restrictions, proximity to boundaries, etc. Ž Tower height Ž Proximity of wind turbines to each other Ž Site accessibility and its effect on construction and maintenance costs. Ž Safety zone of the site regarding proximity of public access. EWSI is committed to responsible siting of its turbines. EWSI will only sell EW15 wind turbines to customers who have locations where there is sufficient wind and where there is responsible personnel either employed by EWSI or from local companies specializing in renewable energy equipment and retained by the customer that can provide long term routine maintenance and emergency repair for the turbine. ii. Utility Factors The EW15 uses an induction generator, which requires the interfacing electrical system to provide generator excitation. Each turbine includes power factor correction capacitors. The turbine installation must consider specific factors regarding the interfacing utility network to provide for a safe and efficient installation. A “Customer Project Questionnaire” is located in the Appendix and should be completed and returned to EWSI. The following utility related factors should be considered: Ž Interconnection Requirements and Standards Ž Buy back rates, contract options, green pricing, net billing, etc. Ž Available line capacity (kVA) Ž Available fault current Ž Voltage and phase configuration of the local utility line Ž Distance to connection point Ž Size and winding configuration of the step down transformer if required Ž To assist EWSI in designing your interface, please complete and return the attached questionnaire.

Construction Planning Considerations To minimize time and cost, the following items should be considered in the planning process: Ž Subcontractor roles and responsibilities Ž Cable trenches (type, length and depth) Ž Control enclosure design Ž Site specific weather extremes Ž Tower foundation type Ž Foundation forming details Ž Site accessibility and road conditions Ž Crane availability and cost Ž Concrete availability and cost Ž Backhoe availability and cost Ž Labor skills and related costs Ž Soil Characteristics Ž Depth to significant frost Ž Allowable bearing capacities. Ž Blasting Ž Availability of hand tools Ž Concrete working tools Ž Fencing materials and security vi. Installation Personnel Considerations The installation of a wind turbine generator requires specialized skills, equipment and experience. EWSI assumes that installation personnel will have the required skills, experience, and equipment to install and/or maintain the wind turbine. Only trained and qualified technicians should attempt to climb the wind turbine tower using IEC/OSHA/ANSI approved practice and equipment. It is very highly recommended that a trained EWSI representative be present for the erection, assembly and commissioning of the wind turbine. The turbine warranty is only valid on EWSI commissioned turbines or those turbines commissioned by EWSI approved and trained installers. In addition the following should also be present at specific times during the installation: Ž 1 to 2 qualified technicians trained in climbing safety to erect and install turbine Ž Qualified crane operator to operate the crane during turbine lifting Ž Certified electrician and/or utility personnel to install cables and wire controllers Ž Additional labor for tasks such as tower assembly vii. Foundation Installation Foundation types and installation are specific to each site. The foundation must be designed for the load conditions expected at that particular site. Refer to IEC standards for Wind Turbines for additional information. Each leg of the tower should be electrically grounded per electrical standards for the region. See the Items “G”, “H” & “I” for information on foundation design loads and foundation layout. The standard foundation for the EW15 can be dug or drilled in locations with cohesive and deep soil conditions. The civil engineer, responsible for the foundation design, should consider site-specific conditions. It may be suitable to excavate for power and control cables at this time. For wire and cable information, see the installation manual to be provided with shipment or contact your EWSI project manager. Please note that the drawings in this section are still being updated to reflect the name change of the machine and company.
